为解决气流对MOPA角多路厅与主放大腔、预放大腔之间的光路的干扰,设计安装了气流屏蔽筒。采用可伸缩的推拉式设计解决了大跨度问题(最大至13 m)。较好地改善了激光在空气中的传输质量,降低了激光传输对天光一号加速器大厅气流的要求,并方便了天光一号加速器大厅中其他工作的进行。
In order to solve the interference of the airflow to the optical path between the MOPA multi-hall and the main amplification chamber and the pre-amplification chamber, an airflow shielding tube is designed and installed. The long-span problem (up to 13 m) is solved with a retractable push-pull design. The quality of laser transmission in the air is well improved, the requirement of laser transmission for the airflow of the hall of the Tiago accelerator is reduced, and the other work in the hall of Tia Guang Accelerator is facilitated.
